The Integrated Modelling of European Migration (IMEM) database was created to provide tables of migration flows among 31 countries in the European Union (EU) and European Free Trade Association (EFTA), as well as to and from the rest of the world.

The estimated migration flows relate to the flows of long-term migrants as defined in the Recommendations on Statistics of International Migration (United Nations 1998).

Estimated flows can be presented by country of origin, country of destination, age and sex, for years 2002 to 2008. They also include measures of uncertainty.
